Operating system limitations - Windows
- ArcGIS software is developed and certified to support file system pathnames with a maximum path length of 260 characters, as defined by MAX_PATH. With the Microsoft release of the Windows 10 Anniversary Update, version 1607, it is possible to extend the 260 character limit for New Technology File System (NTFS) paths. While this is an opt-in behavior of Windows 10 Anniversary Update, doing so can result in unexpected behavior in ArcGIS and is not supported or recommended.
